This article addresses emerging research that both supports and refutes betaine’s capacity to promote muscular adaptations.

This article addresses possible benefits, proposed mechanisms, dosage, and frequency of beetroot juice as an ergogenic aid.

This review analyzes relevant variables involved in acute interference effects of concurrent training (CT) sessions of aerobic exercise followed by strength exercises. The aerobic exercise intensity, mode, volume, duration of recovery interval between exercises, muscle groups involved, and utilization of ergogenic aids are the variables identified in this review. High-intensity interval aerobic exercises result in more pronounced negative effects on strength-endurance exercise but not in maximal strength. Cycling results in more negative effects on strength endurance performance exercise than running. A 4-hour to 8-hour recovery interval seems to be enough to avoid interference on strength-endurance performance. Reduction in strength-endurance performance is located in muscle groups involved in both exercises. Low aerobic exercise volume (3 km) with; 18 minutes of duration does not diminish strength endurance, whereas higher volumes (5 and 7 km) with ;30 and ;42 minutes of duration, respectively, generate impairments. Caffeine, carbohydrate, and beta-alanine are not able to revert the deleterious effect on strength-endurance performance, whereas creatine and capsaicin analog supplementation are. Thus, these variables must be taken into consideration to prescribe and organize a CT session. This information may help coaches to organize exercise sessions that minimize or avoid the impairment in strength performance after aerobic exercises.

Supplements that claim to boost nitric oxide have not been proven to be all that effective since the actual conversion in the blood cell is rather complicated and requires oxygen, which is usually in short supply during exercise or at high altitude. So how does an athlete boost their nitric oxide production?

This article discusses the background, statistics, mechanisms, timing, dosing, influences, and practical applications for the use of caffeine as an ergogenic aid.

This article will explain the interference effect and provide a rationale for why low-intensity steady-state (LISS) cardiovascular training may be a useful tool for those interested in improving their body composition.

This article aims to discuss concurrent activation potentiation (CAP) and the proposed mechanisms underlying it, summarize the available research examining the phenomenon, and provide strategies for its implementation.
